2 RH Replacement cranks needed.

I am looking to replace 2 window cranks at my cabin. one has broken and the other is very loose. I have looked on the site and see no "perfect" match yet and am unsure what is "close enough".

Regards,

Rich

Details:

RH Crank / Silver

Arm: 3"

Arm Holes spaced: 2 1/4"

Hole: 3/8"

Mounting holes: 3

Bottom holes spaced: 1 3/8"

Top hole to bottom right hole: 5 1/4"

That is the one I suspected was right, just wasn't sure how precise the hole/arm dimensions needed to be. Thanks!
